This post aims to analyze the rates of shoreline change in the Scarcies region of North West Sierra Leone along the Atlantic Ocean coastline. The analysis will utilize data from the Digital Earth Africa program Digital Earth Africa program to gain valuable insights into the evolving patterns of coastal movement over time.
The following image is a screenshot showing the visualization of the data through the interactive map displayed below.
The area of interest is highlighted in yellow.
Data points are represented by different colors, indicating shoreline behavior over time. Please refer to Table 1 for the color key and cluster counts.
To navigate the map and select specific layers, utilize the interactive buttons provided.
On the left-hand section, you’ll find a “layers button” that allows easy navigation between different data sets.
Removing the “World” layer improves the level of detail in the satellite images provided by the tmap() function.
